Authorities say the cab driver picked up the two suspects in West Duluth.

While dropping them off, one suspect pulled out a handgun and demanded money.

The second suspect started to choke the cab driver, but the driver was able to break free of the suspects choke-hold and run away.

The suspect with the gun ran after him and fired a shot, but the cab driver was not injured.

The suspect took an undisclosed amount of cash.

Police say the suspects were last seen running eastbound on 8th Street.

The cab driver was taken to St. Mary’s Hospital for a minor injury from being choked.

"I know that he's been treated and released from the hospital for his minor injury that was suffered that night. He's still shaken from the incident, but doing OK physically," said Public Information Officer Jim Hansen, for the Duluth Police Dept.

As the investigation continues, Duluth police are asking anyone with information to call 911.

The cab driver says he is on his way to Governor Dayton's office to discuss funding options for glass–protection shields to be installed in Duluth taxi cabs.
